I used 150 grit for the initial work. I wetted and dewhiskered twice, switching to 220 grit.
I did 3 coats of linseed oil over a three day period. For the first two, I used a rag soaked with BLO, the last day I used the hand method. I did no buffing or shining of the final coat.

This was my first attempt at refinishing. I'm very happy with the results, and grateful for the advice given on this thread.
